Patent GB-650947-A (GB)
Title: The production of new polymers
IPC: C08G61/02
Filed: 1947-09-19
Abstract: A solid polymer is produced when the vapour of an aromatic hydrocarbon having a single or two condensed benzene nuclei in the molecule with two methyl groups substituted in the para positions of one nucleus is pyrolysed by heating to a temperature between 700 DEG and 1000 DEG  C. for not more than 10 seconds and the resulting vapours are cooled to a temperature at which a solid polymer is deposited.  Paraxylene and 1,4-dimethyl naphthalene are specified. Pyrolysis is preferably effected by passing the vapour at about atmospheric pressure or below through a tube for a period of from 0.1 to 1 second.  The vapour may be diluted with an inert gas, e.g. nitrogen or carbon dioxide.  The cooling, which may be on a cold surface producing a film, generally takes place between room temperature and - 80 DEG  C.  By reaction of the pyrolysed vapours with iodine (forming p-xylylene di-iodide) and analysis of the polymer, the monomer is found to contain the groups -CH2- in the para positions.  Condensation and polymerization may be repeated in successive stages at progressively reduced temperatures.  The polymers are thermally stable and are not dissolved or swelled by a number of organic solvents.ALSO:The vapour of an aromatic hydrocarbon having a single or two condensed benzene nuclei in the molecule with two methyl groups substituted in the para positions of one nucleus is pyrolysed by heating to 700 DEG  to 1000 DEG  C. for not more than 10 seconds and the resulting vapours are cooled to a temperature at which a solid polymer is deposited.  P-xylene and 1,4-dimethyl naphthalene are specified.  Reaction of the pyrolysed vapours of p-xylene with iodine vapour results in the production of p-xylylene di-iodide indicating the existence in the vapour phase of the radical CH2.C6H4.CH2 and this is supported by analysis of the polymer. 1,4-Dimethyl naphthalene reacts similarly.  Pyrolysis is preferably effected by passing the vapour through at about atmospheric pressure or below through a tube for from 0.1 to 1 second.  Condensation and polymerization may be repeated in successive stages at progressively reduced temperatures.

Abstract: 815,252. Diode gating circuits. STANDARD TELEPHONES & CABLES Ltd. Aug. 23, 1957 [Aug. 24, 1956], No. 25957/56. Class 40 (6). In a gating or switching circuit the switching control circuit path includes at least one rectifier connected in series opposition to the direction of normal conductivity of a Zener diode. Fig. 4 shows a gate comprising a bridge of crystal diodes D1 ... D4 and a Zener diode D5. In the absence of a control pulse across A, B there is no conducting path to the signal applied across C, D and the gate is " closed." When the amplitude of a control pulse across A, B exceeds the Zener voltage all the diodes D1 ... D5 conduct and the gate is " opened " to a signal across C, D. An increase in the impedance of the gate when " closed " may be achieved by providing a bias via resistors R6, R7 up to the Zener voltage of diode D5. In a modification shown in Fig. 6 two crystal diodes D6, D7 and two Zener diodes D8, D9 are used, the gate being " opened " to the signal across CD when the amplitude of the control pulse from A, B across the whole of the secondary winding of the transformer exceeds the sum of the Zener voltages of D8 and D9. In a further modification shown in Fig. 7 a crystal diode D10 and a Zener diode D11 are used the signals across terminals CD being switched to a load R10 when the switching pulse across terminals A, B biases Zener diode D11 beyond its Zener voltage so that it conducts as does also diode D10.

Abstract: 1,016,279. Tyre treads. FIRESTONE TIRE & RUBBER CO. June 24, 1964 [Oct. 15, 1963], No. 26197/64. Heading B7C. [Also in Division B5] Apparatus for continuously applying unvulcanized rubber to build up a tread or tread and sidewalls on to a buffed tyre or green tyre carcass respectively comprises a calender for producing a calendered rubber strip, means rotatably mounting a tyre carcass to have the strip wound thereon, means for slitting the strip into three ribbons and for removing the central strip, and means for successively changing the width of thestrip and the ribbons incrementally as they are wound on to the carcass to build up a predetermined contour on the carcass. As shown for applying a tread and sidewalls to a green tyre carcass 10 a continuous sheet S of rubber produced by a pair of calender rolls 11 is conveyed through a feed mill 25, which reworks unused material and to which additional rubber may be supplied, back to the rolls 11. The carcass is rotated by contact with the roll 11. Knives 28 cut out a strip 31 which is then cut transversely by a rotary knife 35 (Fig. 5, not shown). The hot strip passes round the rolls 11 and adheres on the carcass 10. The knives 28 are incrementally moved together (see Fig. 7, not shown) on each rotation of the carcass. To provide tread shoulders, knives 38 are pressed against the roll 11 to cut out a centre ribbon 40 which is cut transversely by a knife 45 (Fig. 5, not shown), and returned to the feed mill. The width of the outer ribbons 39 is decreased by incrementally moving the knives 28 together and the knives 38 apart until the required contour has been built up. The ribbons 39 are cut off, the knives 38 are lifted from the roll 11, and the knives 28 are rapidly brought together and lifted to return the sheet S to a full unslit width (see Fig. 4, not shown). To avoid air being trapped between the carcass and the strip, or between successive turns of the strip, the sheet S is vented by a perforating roller. The knives are all pneumatically operated.

Filed: 1960-07-28
Abstract: 956,450. Automatic voltage control. WESTERN ELECTRIC CO. Inc. July 28, 1960 [Aug. 5, 1959], No. 26301/60. Heading G3R. An A.C. source 10 for supplying a load 11 which may vary is rectified by PNPN switches 15, 16 which are the functional equivalents of gas thyratrons and by diodes 13, 14. A detector 20 detects load or line voltage variations and its output is applied, via an amplifier 21, to a trigger and control circuit 36 which determines the output voltage of the rectifier circuit. Control is applied to the switches 15, 16 by a current pulse derived from a capacitor 39 which discharges through a unijunction transistor (double-base diode) 37. The current pulse necessary to turn on the switches 15, 16 is derived from a trigger circuit consisting of a resistor 38, capacitor 39, diodes 23, 24 and the unijunction transistor 37. If the voltage between the bases of the transistor 37 increases as a result of the output voltage across the load 11 increasing, the capacitor 39 will have to charge to a higher value before being able to discharge through the transistor, the time of turn-on or the firing-angle of the switches 15, 16 is delayed and the rectified output voltage reduced. When the load voltage decreases, the capacitor is required to charge to a lesser value before discharging and the switches 15, 16 conduct for a longer portion of the A.C. cycle. Single wave rectification may be provided using one switch only.

Abstract: 1,046,277. Waveguide harmonic filters. COMPAGNIE FRANCAISE THOMSON-HOUSTON. July 3, 1963 [July 3, 1962], No. 26375/63. Heading H1W. A filter for absorbing parasitic signals, e.g. those propagated in unwanted higher modes, comprises a main waveguide 1 communicating with a number of auxiliary dissipative waveguides 2 stacked with their broad faces (dimension a) face to face. The auxiliary waveguides are dimensioned to be beyond cut-off within the pass-band of the filter. Higher frequencies within the rejection band are absorbed by dissipative loads 3. In order to counteract the effect of the auxiliary guides upon the impedance of the main guide within the pass band, -the latter is provided with a thick conductive septum 4 extending between the narrow walls. In the modification of Fig. 2a (not shown), which uses a coaxial line instead of a main waveguide, the same result is achieved by providing discs 6 on the inner conductor opposite each of the auxiliary guides 2. The filter may consist of several sections each having auxiliary guides of different dimensions and discs 6 of different diameter. Reference has been directed by the Comptroller to Specification 903,889.

Title: Improvements in warp stop motions for looms
IPC: D03D51/20
Filed: 1931-09-22
Abstract: 389,825. Warp stop-motions. FURUYA, R., 119, Kashiwagi, Yodobashi Machi, Toyotama Gun, Tokio. Sept. 22, 1931, No. 26470. [Class 142 (i).] In a warp stop-motion for looms having in each heddle frame heddles mounted on supporting bars and adapted, when a warp thread slackens or breaks, to drop into the path of an oscillating feeler plate operatively connected to a loom stopping device, the feeler plate is mounted on the heddle frame and operates through a reciprocable member on the reed leg, the member, upon interception of the feeler plate by a heddle, being displaced from its normal position on the reed leg, against a yielding control, to operate the stop mechanism. Across each of the vertically reciprocating heald frames 2, Figs. 2 and 3, an oscillating detector plate 9 is secured to a rock shaft 10. Outside the frames the shaft 10 carries a spring-pressed lever 11 provided with a pin 13, Fig. 5, adapted to be engaged by an arm 40 on an axially movable rod 14 and to be rocked thereby. The rod 14 passes through a pin 16 secured to a bracket 17 on a reed leg 18 and is resiliently connected to the reed leg by a compression spring 19 disposed between the leg and a collar 20 on the rod, the movements of the reed thus reciprocating the rod 14. The end 21 of the rod 14 is connected by a cord 22, passing over a pulley 24, Fig. 3, on the reed frame 25, to a spring-pressed pin 26 which normally holds a sector-shaped hammer 31 in a raised position. When a warp thread breaks, the corresponding heald drops and prevents the oscillation of the detector plate 9. This prevents the backward movement of the rod 14, and the reed leg 18 in its movement thrusts the pin 16 along the rod 14 against the action of the spring 19 and thereby exerts a pull on the cord 22. The cord 22 releases the hammer 31 which drops and disposes a pin 33 provided on it opposite an abutment plate 36 mounted on the starting handle 35. The pin strikes the plate as the reed frame returns and frees the handle from its retaining catch (not shown), an inclined plate 37 on the handle moving the pin 33 from the path of the abutment 36 as the natural resilience of the handle moves it back to its inoperative position.
